Embodiment Construction

[0052]The present invention includes systems and methods for use in adjusting seed planting depth and row unit down pressure to account for varying levels of soil moisture in a field when planting to minimize occurrences of late emerging corn seedlings.

[0053]FIG. 3 illustrates one example of a system which includes a planter 4 having a control system 5. The control system 5 may include an intelligent control 11 operatively connected to a monitor 2. There may be a plurality of row units 6. For each row unit 6, there is an actuator 8 and sensors 7, 9. The sensors 7, 9 may include a soil moisture sensor, a seed to soil contact sensor, soil temperature sensor and seed trench depth sensor for adjusting seed planting depth and row unit down pressure on-the-go while planting.

[0054]FIG. 4 illustrates another example of the invention. As shown in FIG. 4, an intelligent control 11 is operatively connected to a monitor or display 2. The intelligent control unit 11 is also operatively connected...

Abstract

An on-the-go monitor and control means and method for an agriculture machines includes on-the-go soil sensors that can be used to control tillage and seeding depth. On seeder implements, the sensors provide information that affects uniform plant emergence.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to agricultural machines, and more specifically, to on-the-go sensors that measure soil parameters affecting optimum planting and tillage depth. An electronic control system may automatically adjust planting or tillage depth on-the-go based on measured soil parameters.BACKGROUND OF THE INVENTION[0002]In crops like corn, uniform seed germination and plant emergence are critical to achieve maximum yield potential. According to The Ohio State University Extension Fact Sheet Tips to Reduce Planter Performance Effects on Corn Yield, “Uneven emergence affects crop performance because competition from larger early-emerging plants decreases the yield from smaller later-emerging plants.”“Emergence delays of 10 days or more usually translate to growth stage differences of two leaves or greater. Therefore, if two plants differ by two leaves or more, the younger, smaller plant is more likely to be barren or produce nubbins.” It...
